w> IP addresses are likely to be all on the same subnet
| Adv: ZoneCheck
| To avoid loosing all connectivity with the authoritative DNS in case
| of network outage it is advised to host the DNS on different networks.
|
| Ref: IETF RFC2182 (Abstract)
| The Domain Name System requires that multiple servers exist for every
| delegated domain (zone). This document discusses the selection of
| secondary servers for DNS zones. Both the physical and topological
| location of each server are material considerations when selecting
| secondary servers. The number of servers appropriate for a zone is also
| discussed, and some general secondary server maintenance issues
| considered.

: All the servers are likely to be on the subnet 67.225.157.64/28, try
